34 QUADRUMANA. 



Chimpanzee. In the young animal, the forehead and skull ap- 

 pear well developed and somewhat human ; in the adult, the 

 bones of the face are so increased in size that they throw the 

 skull backwards, which, combined in its effect with other differ- 

 ences, takes away the resemblance, which is seen in the younu;, 

 to the human face. The arms are so long that they reach the 

 ground, or nearly so, when the animal stands erect ; and the 

 palms of the hands show lines and papillae, like those of ma-n. 

 The ears are small ; the eyes dark and round ; the throat is 

 swollen, the skin about it being loose and folded, and enveloping 

 a double membranous sac, which connects with the larynx or 

 wind-pipe, and becomes inflated when the animal expresses pleas- 

 ure or anger. The body is stoutly built and very muscular ; 

 the belly round and protuberant ; the hair is of a reddish brown 

 hue, long and coarse. The Ornng has no tail or cheek 

 pouches. A very marked characteristic is the disproportion be- 

 tween the size and length of the arms, as compared with the 

 legs, which, viewed in connexion with the long and hooked hands, 

 indicates that the animal is, more than the Chimpanzee, formed 

 to live on trees. Among the branches, he moves with surprising 

 facility. By weaving these together, he constructs a sort of 

 rude hut, which he seldom leaves, except when forced by the 

 calls of appetite. In Borneo, the natives call the two species 

 found there, mias-kassar and mias-pappan. Of these the latter 

 is much the larger and more powerful, and justly named Satyrus, 

 from his ugly face and disgusting callosities. Some naturalists 

 consider the Orang of Sumatra to be a distinct species. 



The Orang may be ranked as the largest of the apes. A 

 specimen from Borneo was in height five feet ten inches, and one 

 from Sumatra reached the enormous stature of seven feet six 

 inches. Those animals are described by persons who have seen 

 them in their native climes, as "leading a solitary life, more than 

 two or three never being found together;" and as "roused from 

 their habitual dullness by nothing but hunger or the approach 

 of danger." Their strength is so great they can not be safely 

 encountered except with fire-arms. A female Orang snapped a 

 strong spear asunder, after receiving many wounds. Hence, 

 the natives of Borneo hold these animals in especial dread, and 

 carefully avoid them.
